@DJ, I posted earlier on the EMIC2 voice module, something is wrong with SendSerial, it's causing the EZ-B to reset as well as tested on two dfferent ez-b modules and a serial lcd module.

Thank you so much DJ for all hard work, I am very happy with all the latest improvement in ARC. Would it be possible to add cut, copy and paste capability in EZ script in a future update?
Thanks DJ
